Description

Technical Field

[0001] This utility model relates to the field of crimping equipment technology, and specifically to a crimping assembly fixture. Background Technology

[0002] According to the publication number CN212008831U, named "PCBA Online Testing Device", the size of the PCBA board is controlled by controlling the distance between the conveyor belts. When the PCBA board is conveyed between the upper and lower test fixtures, the upper and lower test fixtures hold the PCBA board to perform testing.

[0003] Since the position of the PCBA board is controlled by a conveyor belt, and the upper and lower test fixtures locate the PCBA board, the PCBA board on the conveyor belt may not make good contact with the test fixture during testing due to insufficient stability, resulting in inaccurate test results or test failure. To address this, we propose a crimping assembly fixture. Utility Model Content

The platform unit includes a sliding box with internal partitions. First lead screw motors mounted on both sides of the sliding box drive baffles to slide vertically. The partitions are connected to the belt, and a second lead screw motor on the partition engages with a sliding table located on the partition for lifting. A platform is separately mounted on the sliding table, and the platform and baffles are fitted together to form a cavity for accommodating PCBA boards, which are then simultaneously lifted by the first and second lead screw motors.

[0009] Preferably, the second lead screw motor drives the slide table to slide vertically, and the slide table drives the platform to rise and fall.

[0010] Preferably, the slide has multiple protrusions and the bottom of the platform has corresponding recesses.

[0011] Preferably, the first lead screw motor drives the slider to slide vertically, and an extension rod is connected between the slider and the baffle.

[0012] Preferably, the belt conveyor unit includes a column and a pair of side plates mounted on the column, with space between the side plates for the slide to be lifted.

[0013] Preferably, it also includes a lead screw stepping unit, and the platform unit is connected to the lead screw stepping unit and the belt conveyor unit to form a dual drive.

[0014] (III) Beneficial Effects

[0015] This utility model provides a crimping assembly fixture. It has the following beneficial effects:

[0016] 1. By changing the PCBA board from being placed on a conveyor belt to having the conveyor belt control the overall movement of the platform unit, and then having the first and second lead screw motors synchronously lift it to form relative compression and lift it to the designated position, the instability during lifting is avoided.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See attached document Figure 1-5This utility model discloses a pressing assembly fixture, including a base 1 and a belt conveyor unit 2 mounted on the base 1, and a platform unit 3 slidably mounted on the belt conveyor unit 2. The belt conveyor unit 2 includes a column and a pair of side plates 21 mounted on the column, with space between the side plates 21 for a sliding table 38 to lift. The platform unit 3 includes a sliding box 31 with a partition 36 installed inside. The partition 36 facilitates the installation of the sliding box 31. First screw motors 32 are installed on both sides of the sliding box 31, which can drive baffles 35 to slide up and down. The partition 36 is connected and fixed to the belt. By driving the partition 36, the overall displacement of the platform unit 3 can be controlled. In contrast, the prior art places the PCBA board on the surface of the conveyor belt, avoiding instability during the sliding process. Furthermore, the second screw motor 37 on the partition 36 and the sliding table 38 located on the partition 36... The platform 38 is lifted and coordinated. Parallel slide rails are also provided on the partition 36. The slide rails cooperate with the platform 38 to achieve sliding. The lead screw connected to the second lead screw motor 37 can drive the platform 38 to rise and fall, thereby driving the platform 39 to rise. The second lead screw motor 37 drives the platform 38 to slide vertically, and the platform 38 drives the platform 39 to rise and fall. The platform 38 is provided with multiple protrusions, and the bottom of the platform 39 is provided with corresponding recesses. The platform 38 and the platform 39 form a separate cover-and-cover configuration. An inner groove is provided around the bottom of the baffle 35. The size of the inner groove is the same as the size of the PCBA board. The baffle 35 can cover the PCBA board. The baffle 35 and the platform 39 are in close contact, so that the PCBA board can be lifted synchronously by the first lead screw motor 32 and the second lead screw motor 37, forming relative compression and lifting it to the designated position, avoiding instability during lifting.

[0025] In this embodiment, the first lead screw motor 32 drives the slider 33 to slide vertically, and an extension rod 34 is connected between the slider 33 and the baffle 35.

[0026] In this embodiment, a lead screw stepping unit is also included. The lead screw on the lead screw stepping unit is connected to the lower part of the platform unit 3, and the belt of the belt conveyor unit 2 is connected to the upper part of the platform unit 3. The platform unit 3 is connected to the lead screw stepping unit and the belt conveyor unit 2 to form a dual drive.
